Using your Campagnolo EKAR Crankset is easy. First, make sure to pair it with a Campagnolo Pro - Tech bottom bracket as required. When you're out riding on gravel, the 13 - speed drivetrain and the narrow - wide chainring design will give you smooth and efficient pedaling. To change the alloy rings, you don't need to take the whole crankset apart. Just follow the simple steps for a quick swap. As for maintenance, keep the external crank bearings clean. You can use a mild cleaner and a soft cloth to wipe them down after a dirty ride. Check the chain regularly for wear and replace it when needed. And make sure to store your bike in a dry place to prevent any rusting of the steel alloy parts. Enjoy your gravel adventures with this great crankset!
